The Imperial General of the Right. One of the Twin Shields of Yamato, along with Mikazuchi.
His face is always covered by a mask.
He is skilled in both the arts of war and peace, earning him the trust of both the people and the emperor.
Oshtor came from a low-ranking family that was noble only in name. Wanting to become a soldier like his father, he left his hometown and became a rank-and-file guard. He intended to return home after rising through the ranks, but instead was promoted to the Imperial Guard of the Right after his deeds caught the Mikado's attention.
